User manual ALFA ROMEO 166

[. . . ] Dear Client, Thank you for choosing Alfa Romeo. Your Alfa 166 has been designed to guarantee the safety, comfort and driving pleasure typical of Alfa Romeo. This booklet will help you to get to know the characteristics and operation of your vehicle. The following pages contain all the indications necessary for you to be able to maintain the high standards of performance, quality, safety and respect for the environment which characterise this Alfa 166. [. . . ] The choice of materials, techniques and particular devices are the result of work which has made it possible to drastically reduce the harmful effects on the environment and guarantee respect for the severest international norms. USE OF NON-TOXIC MATERIALS None of the components of the vehicle contain asbestos. The padding and the climate control system do not contain CFCs which are held to be responsible for the destruction of the ozone layer. The colouring agents and the corrosion inhibitors used on the nuts, screws and bolts do not contain cadmium or chrome which could pollute the atmosphere or water tables. EMISSION REDUCING DEVICES (Petrol engines) Catalysts The exhaust system is fitted with a system of catalysts formed of precious metal alloys housed in a stainless steel container which withstand high operating temperatures. The catalysts convert unburned hydrocarbons, carbon monoxide and nitric oxides in the exhaust gas (even in minimal quantity, thanks to the electronic ignition and injection systems) into non polluting compounds. 130 WARNING Due to the high temperature reached while the catalysts are working, it is advisable not to park the car over inflammable material (paper, fuel oils, grass, dry leaves, etc. ). Lambda sensors The lambda sensors detect the oxygen content in the exhaust gas. The signals transmitted by the Lambda sensors are used by the electronic control unit of the injection-ignition system to adjust the air-fuel mixture. Anti-evaporation system (only petrol versions) As it is impossible, even when the engine is switched off, to prevent the formation of fuel vapours, a system has been devised which traps them in a special carbon container. During operation of the engine these vapours are withdrawn and sent to combustion. EMISSION REDUCING DEVICES (diesel engines) Oxidising catalytic converter Converts the polluting substance in the exhaust gases (carbon monoxide, unburnt hydrocarbons and particulate), thus reducing the fumes and smell that are typical of diesel engines. The catalytic converter consists of a stainless steel case that houses a ceramic honeycomb coated with noble metal used as a catalyst. Exhaust gas recirculation system (E. G. R. ) This system recycles, i. e. re-uses, a varying percentage of the exhaust gases depending on engine operating conditions. It is used, when necessary, to control nitric oxides. 131 GETTING THE BEST OUT OF YOUR CAR Reading this chapter and following the advice, recommendations and specification given in it will make it possible for you to get the best from your vehicle in terms of safety, performance, reliability and length of life. This chapter mostly deals with procedures of a general nature. However, in some cases, it may deal with exclusive and particular operations. Pay close attention therefore to the information given as this will allow you to exploit your vehicle to the full.
